Video-based Assessments of Colonoscopy Inspection Quality Correlate with Quality Metrics and Highlight Areas for Improvement

Background & Aims Adenoma detection rate (ADR) and serrated polyp detection rate (SDR) vary significantly among colonoscopists. Colonoscopy inspection quality (CIQ) is the quality with which a colonoscopist inspects for polyps and may explain some of this variation. We aimed to determine the relationship between CIQ and historical ADRs and SDRs in a cohort of colonoscopists and assess whether there is variation in CIQ components (fold examination, cleaning, and luminal distension) among colonoscopists with similar ADRs and SDRs. Methods We conducted a prospective observational study to assess CIQ among 17 high-volume colonoscopists at an academic medical center. Over 6 weeks, we video-recorded >28 colonoscopies per colonoscopist and randomly selected 7 colonoscopies per colonoscopist for evaluation. Six raters graded CIQ using an established scale, with a maximum whole colon score of 75. Results We evaluated 119 colonoscopies. The median whole-colon CIQ score was 50.1/75. Whole-colon CIQ score (r=0.71; P<.01) and component scores (fold examination r=0.74; cleaning r=0.67; distension r=0.77; all P<.01) correlated with ADR. Proximal colon CIQ score (r=0.67; P<.01) and component scores (fold examination r=0.71; cleaning r=0.62; distension r=0.65; all P<.05) correlated with SDR. CIQ component scores differed significantly between colonoscopists with similar ADRs and SDRs for most of the CIQ skills. Conclusion In a prospective observational study, we found CIQ and CIQ components to correlate with ADR and SDR. Colonoscopists with similar ADRs and SDRs differ in their performance of the 3 CIQ components—specific, actionable feedback might improve colonoscopy technique

Behavioral interventions to reduce inappropriate antibiotic prescribing: a randomized pilot trial

Background: Clinicians frequently prescribe antibiotics inappropriately for acute respiratory infections (ARIs). Our objective was to test information technology-enabled behavioral interventions to reduce inappropriate antibiotic prescribing for ARIs in a randomized controlled pilot test trial. Methods: Primary care clinicians were randomized in a 2 × 2 × 2 factorial experiment with 3 interventions: 1) Accountable Justifications; 2) Suggested Alternatives; and 3) Peer Comparison. Beforehand, participants completed an educational module. Measures included: rates of antibiotic prescribing for: non-antibiotic-appropriate ARI diagnoses, acute sinusitis/pharyngitis, all other diagnoses/symptoms of respiratory infection, and all three ARI categories combined. Results: We examined 3,276 visits in the pre-intervention year and 3,099 in the intervention year. The antibiotic prescribing rate fell for non-antibiotic-appropriate ARIs (24.7 % in the pre-intervention year to 5.2 % in the intervention year); sinusitis/pharyngitis (50.3 to 44.7 %); all other diagnoses/symptoms of respiratory infection (40.2 to 25.3 %); and all categories combined (38.7 to 24.2 %; all p < 0.001). There were no significant relationships between any intervention and antibiotic prescribing for non-antibiotic-appropriate ARI diagnoses or sinusitis/pharyngitis. Suggested Alternatives was associated with reduced antibiotic prescribing for other diagnoses or symptoms of respiratory infection (odds ratio [OR], 0.62; 95 % confidence interval [CI], 0.44–0.89) and for all ARI categories combined (OR, 0.72; 95 % CI, 0.54–0.96). Peer Comparison was associated with reduced prescribing for all ARI categories combined (OR, 0.73; 95 % CI, 0.53–0.995). Conclusions: We observed large reductions in antibiotic prescribing regardless of whether or not study participants received an intervention, suggesting an overriding Hawthorne effect or possibly clinician-to-clinician contamination. Low baseline inappropriate prescribing may have led to floor effects. Trial Registration ClinicalTrials.gov: NCT01454960.
